Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

aparently "__drbd_set_in_sync" is called, even though there is no sync.
this should not happen, since in "normal operation" no bits are out of
sync, so nothing could be set in sync.

you had some sync going on?
did it terminate ok?
can you "fix it" by doing
	drbdadm disconnect all
	# wait for it to go "StandAlone", then
	drbdadm connect all

if you did nothing "stupid", maybe we have some race condition
or other logic bug for resetting the "SYNC_STARTED" bit somewhere ...
